Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0736R5L is determined by the following criteria:

• Resistance Value: Must be 36.5 Ohms
• Package Type: Must be 0805 (2012 Metric) with identical physical dimensions (0.079" L x 0.049" W)
• Composition: Must be thin film construction
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating
• Termination Count: Must have 2 terminations

The substitute part 8-1625868-1 meets all core substitution criteria. Enhanced specifications in tolerance (±0.1% vs ±1%) and power rating (0.25W vs 0.125W) represent improvements that maintain backward compatibility while providing additional design margin.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0736R5L and 8-1625868-1 are active production components with ROHS3 compliance and MSL 1 rating, suitable for standard PCB assembly processes. The substitute part 8-1625868-1 provides enhanced specifications: tighter tolerance (±0.1%), higher power dissipation capability (0.25W), and lower temperature coefficient (±25ppm/°C). These improvements do not introduce incompatibility with designs specified for the original part. Physical footprint compatibility is maintained, with the substitute height (0.026" maximum) remaining within typical PCB assembly tolerances. Selection between these parts depends on procurement availability and design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can 8-1625868-1 be used as a direct replacement for RT0805FRE0736R5L?

A: Yes. Both parts share identical resistance value (36.5 Ohms), package type (0805), composition (thin film), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). The substitute part meets all core electrical and mechanical requirements for direct substitution.

Q: What are the key differences between these parts?

A: The substitute part 8-1625868-1 offers three enhancements: tolerance of ±0.1% compared to ±1%, power rating of 0.25W compared to 0.125W, and temperature coefficient of ±25ppm/°C compared to ±50ppm/°C. These represent improved performance specifications that maintain backward compatibility.

Q: Are there any height or footprint concerns?

A: Both parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). The substitute part has a maximum seated height of 0.026" compared to 0.024" for the original part. This 0.002" difference remains within standard PCB assembly tolerances and does not affect footprint compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RT0805FRE0736R5L and 8-1625868-1 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) rating. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Which part should be selected for new designs?

A: Selection depends on procurement availability and design specifications. For applications requiring tighter tolerance control or higher power dissipation margin, the 8-1625868-1 provides enhanced specifications. For cost-optimized designs where the original specifications are sufficient, the RT0805FRE0736R5L remains appropriate.
